SPINNING-FRAME.

SPECIFICATION forming part of Letters Patent No. 440,200, dated November 11, 1890.

Application filed June 22, 1888. Serial No. 277.925. (No model.)

To all whom t may concern.-

Be it known that we, JOHN SCOTT and JAMES A. MCAVOY, of VVillimantic, in the county of Windham and State ofy Connecticut, have invented certain new and useful Improvements in Spinning-Frames, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

Our improvement relates to the class of machines used in spinning yarn, thread, and the like; and our object is to provide an apparatus by means of which time and labor may be saved in the dofng of the spindles after the bobbins borne by them have become filled.

To this end our improvement consists of a spinning-frame bearing a clotting-rod ext-ending lengthwise of the frame in position to raise and lower all of the guide-blocks along the frame at one time, in combination with the hinged guide-blocks; and it further consists in details of the several parts making up the device and their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a view in front elevation of part of a spinningfranie illustrating,r our invention. Fig. 2 is a detail view, in cross-section, of the frame, showing parts in side elevation with the guideblocks down. Fig. 3 is a like detail View, in vertical cross-section, of the frame, showing the guide-blocks lifted.

In the accompanying drawings, the letter d denotes the spinning-frame as a whole; b, the top rail; c, the ring-rail, and CZ the spindles, mounted and driven in the ordinary manner and supporting the usual bobbins. 'lhe thread-guide b2 on the hinged block b overhangs the spindle when the thread c is being spun in such manner that the guide must be lifted out of the way, as by throwing up the block, in order to place the bobbins on or to remove them from the spindles. These blocks are usually thrown back one by one by the operative in dofiing the spindles, and this takes considerable time. In any suitable position, preferably to the side parts of the frame, I pivot the doffer-levers f, that support a dotfer-rod g, that extends completely across the frame from side to side far enough to underlie all of the hinged guide-blocks b. This doffer-lever and its rod are preferably arranged as shown in the drawings, the rod being borne on an outwardly-projecting arm f of the lever and underneath the threadguide and in front of a slug-hook h, the ofce of which is to catch and remove any bunch or slug that may be on the yarn as it is drawn past the hook and onto the bobbin.

When the doffer-levers are lifted, as shown in Fig. 3 of the drawings, the rod lifts at once all of the guide-blocks and leaves the spindles along the whole length of the spinningframe free, so that they may be all doffed and empty bobbins substituted. The guide-blocks are then returned to their proper position by simply pressing down on the doffer-levers, which throws the rod g against the projecting arms of the slug-hooks and trips the blocks into proper position for the thread to be led through the guides and wound about the bobbins.

\Ve claim as our inventionl. In a spinning-frame,in combination with the hinged guide-blocks, the doer-rod eX- tending lengthwise of the frame and beneath the blocks, and the doier-levers pivoted to the frame and secured to the rod, all substantially as described.

2. In a spinning-frame, in combination with the dofter-levers pivoted to the frame, the thread-guide blocks hinged to the frame and each having a downwardly-projecting part on the under side, and the dotfer-rod secured to the levers and extending lengthwise of the frame beneath the guide-blocks and in front of the downward projection on said blocks, all substantially as described.

3. In a spinning-frame, in combination with the dofter-lcvers pivoted to \the frame, the guide-blocks hinged to the frame overhanging the spindle and each supporting a threadguide and a dowi'iwardly-proj ectingslug-hook, and the doffer-rod secured to the levers and extending lengthwise of thef rame beneath the guide-blocks and in front of the slug-hook, all substantially as described.
